问题     The "Karat" marking on jewelry tells you what proportion of gold is mixed with other metals. If 14 parts of gold are mixed with 10 parts of base metal, the combination is called 14 Karat (14K) gold. The higher the Karat rating, the higher the proportion of gold in the object. The lowest Karat gold that can be marketed in the United States is 10-Karat gold. Jewelry does not have to be marked with its Karat quality, but most of it is. If there is a Karat quality mark, next to it must be the U.S. registered trademark of the person or company that will stand behind the mark, as required by the National Gold and Silver Stamping Act. [br] The Stamping Act is ______.

选项 A、a regulation for tax
B、rule of law
C、a law that makes such stamping mandate .
D、an implement

答案 C

解析 文中最后一句的Stamping Act指印花税法,即C项所说的“制订印花税授权的法令”,而不是A项所说的税收规则,B项所说的一项法规和D项所说的一种手段。
